How common is visible deformity after injury in shoulder dislocation?

A dislocated shoulder may look out of place because the upper arm bone has moved away from its normal position in the shoulder socket. The shoulder may appear squared off, uneven, or different from the other side. Severe pain, guarding, swelling, and inability to move the arm often occur alongside the change in shape.

A visible change can suggest a serious injury, but appearance alone cannot show whether nearby nerves, blood vessels, bones, or soft tissues are also affected. A clinician usually checks circulation, sensation, and movement and arranges imaging when needed.

Keep the arm still in the position that feels least painful and support it with a sling or folded cloth if available. Remove rings or a watch before swelling increases. Do not push the shoulder back into place, force movement, or let someone without medical training attempt a reduction. Arrange urgent medical assessment after an injury with a new shoulder deformity.

Seek emergency help immediately if the hand becomes cold, pale, blue, numb, or unusually weak, or if pain is severe or worsening. Urgent assessment is also needed after a fall, collision, or blow when the shoulder shape has changed, even if pain later eases. These signs can accompany damage that needs prompt treatment.

Ask whether the shoulder is dislocated, whether imaging is needed, and how the nerves and blood flow were checked. You can also ask how long to use a sling, which movements to avoid, and when supervised rehabilitation should begin.
